Click Tools-Options in the oCam menu to display the following settings window. Learn about the Recording-General tab.
Include the cursor
- It is checked by default. If checked, the mouse cursor of recorded video is included. If not checked, the mouse cursor of recorded video is not included.
Hide drag cursor in recording area
-By default, the check is cleared. If checked, the drag cursor in the middle of the recording area disappears.
Frames Per Second (FPS) - It is set to 30 by default and can be up to 120 FPS. 30 FPS is suitable for recording general screens. It is recommended to record 60 FPS or more for racing games or games that change screens rapidly during game recording.
Among the built-in codecs, MPEG-2 and MPEG-1 codecs are fixed at 30 FPS without being affected by the codec setting.
Keyframe interval - By default, it is set to 5. If the keyframe interval is 5, keyframes are generated every 5 seconds, if 1, every 1 second, if 2, every 2 seconds, if n, then every second.
Decoder Resolution Compatibility - Some video players have a problem with blurry playback of video files that are not set to a specific resolution size. (For example, bear player)
By default, the width is set to a multiple of 8, and the vertical is set to a multiple of 4. If the horizontal size of the recording area specified by the user does not fit to the multiple of 8, it is forced to a multiple of 8. The vertical size of the recording area does not fit to the multiple of 4. If not, the vertical size is applied in multiples of four.
For example, if the decoder resolution is set to "multiple of 8 and vertical of 4" and the recording area is 427x241, the horizontal size is 427, but since it is not divided by 8, the horizontal resolution is corrected to divide by 8 Is 424, and the vertical size is not divided by 4, so it is applied to 240 so that the recording area is finally set to 424x240.

[HOWTO]Frequently Asked Questions about Variable frame rate (VFR) and Constant frame rate (CFR)
The following is a brief summary of the FAQs about frame rate mode.
Q. What exactly is variable frame rate?
A. If there is a video file recorded for a certain period of time, if the number of frames per second is the same, then it is a fixed frame rate. If the number of frames per second is different, it is a variable frame rate.
For example, if you record a screen for 5 seconds and record exactly 30 frames per second, you have a fixed frame rate, and you record a screen for 5 seconds, in the middle of 3 to 4 seconds, not 25 frames per second, but 25 frames per second. 30 is the variable frame rate.
The exception is the last frame count. You recorded for 4.5 seconds and recorded exactly 30 frames every second up to 4 seconds ago, but the last 0.5 seconds can be less than or equal to 30 frames.
Q. If I was recording a game at 60 FPS with OCAM and set to variable frame rate mode, and the system is so good that it doesn't hang at all, will it be recorded at a fixed frame rate?
A. If the rack doesn't hang at all, it will record at a fixed frame rate instead of a variable frame rate. If you have all 60 frames per second, it's because of the fixed frame rate.
Q. If you record a game at 60 FPS for 5 seconds on Ocam and exactly 30 frames per second (full 150 frames), is it a variable frame rate?
A. This creates a movie file recorded at a 30 FPS fixed frame rate. Recording at 60 FPS does not result in a variable frame rate if no 60 FPS frames are produced. The variable frame rate must be variable in number of frames.
Q. Why is it that when the recording is output at 60FPS and the game is output at 60FPS in the variable frame rate mode, but the recorded file shows 59.xx?
A. When the game screen is output at 60FPS, the screen is not output at 60FPS at the correct interval. When the game screen is output at 60FPS, the screen should be output in the unit of 1000ms / 60 = 16.66666666666667ms, but it is recorded as 59.xxx because there is a slight millisecond difference.
In addition, the FPS calculation on Ocam shows the value calculated on the FPS in 200 millisecond units, so it can be 59.xxx even when the output is 60 FPS.
To work around this issue, change the settings of the ocam to a fixed frame rate.
Q. If the computer's performance is low when recording at a fixed frame rate, will it be recorded at a variable frame rate?
A. No. Recording is at a fixed frame rate. However, due to the low performance of the computer, for example, if you excessively record at a fixed frame rate of 120 FPS, a movie file recorded at 120 FPS will be created, but the recorded file may be severely racked or racked during recording.
